The Merseyside outfit have had an inconsistent start to the season, taking just one Premier League win at Anfield so far, but Houllier believes that Rodgers's system will bring success to the club.
"I am pleased with the way Brendan makes the team play," Houllier told the club's official website. "He plays the right way and I'm pleased he's given a chance to some of the young players. Some are very good.
"[Raheem] Sterling could be a major player for the club in the future and at the moment he just needs to be a little more composed, particularly in the final move of his game. Suso, Andre Wisdom and Joe Allen are all good players and it's very good for the future of the club."
Houllier managed the Reds between 1998 and 2004.
